The LA-based alt-pop quartet Echosmith paid a visit to 'The Today Show' this morning (Sept. 10) to perform their hit single, 'Cool Kids,' from their buzzed-about debut album, 'Talking Dreams,' that was released last year. You can watch their performance above.

Fronted by 17-year-old singer Sydney Sierota, the band -- which is comprised of all siblings -- is also preparing to release a brand new music video for 'Cool Kids' tomorrow via MTV (see the original music video below). The single is currently sitting on top of the iTunes Alternative chart.

The band will kick off an extensive U.S. tour next month with a few appearances alongside American Authors as part of the Honda Civic Tour. After that, Echosmith will be opening up for Neon Trees followed by their own run of headlining gigs. You can get more info on their complete tour itinerary here.
